Hooked up my boat for the first time and noticed that the brake lights work but nothing else. Fuses look good, I don't know much electrical. The trailer lights work fine on my other truck. Any ideas? Could there be another fuse elsewhere not under the hood?

There are a lot of non standard hookup's, the trailer was wired to the old truck, You need to change the trailer wiring to the truck which is correct.

When was the last time you had it hooked up to your other truck? Are you using the 4 pin or 7 pin connector or some sort of adapter? Have you used a multi meter to make sure you are getting power at the plug when the tails, blinkers, and flashers are on? If not, those would be some things I would check.
